I have a special affinity for bluegrass and most all of the above already have a place in my collection. Some of the early Bill Monroe on Decca are just great. Stanley Brothers, too. In addition to those already mentioned, there is the Osborne Family in various combinations, the Dillards (some of whom were the Darlings on the old Andy Griffith Show), Bela Fleck did a couple of "Bluegrass Session" release including Earl Scruggs and others. I will throw out there Norman Blake (virtuoso guitar), as well. The Nitty Gritty Dirt Band "Will the Circle Be Unbroken" is a classic as is "Symphonian Dreams". Kind of a hybrid bluegrass/rock/country that I've always liked is the Ozark Mountain Daredevils, especially the "Men From Earth" LP.
